This combination is often used to bootstrap installations due to its simplicity and effectiveness.
Breaking this command down, curl -fsSL is a powerful command-line tool used for transferring data with URLs. The options -fsSL are critical: -f makes curl fail silently on server errors, -s ensures silent mode (suppressing error messages), -S makes sure errors are shown when -s is used, and -L allows curl to follow redirects. This combination ensures the installation script is fetched securely and silently without unnecessary interruptions.
Once the script is downloaded, it’s immediately passed to bash, which is the Unix shell, to run. Make sure you have administrator privileges when executing this command to allow system-level modifications, which is essential for setting up the necessary dependencies for Claude Code.
Installing Claude Code on Windows
irm https://claude.ai/install.ps1 | iexFor Windows users, the installation process leverages PowerShell’s command line. irm is an alias in PowerShell for Invoke-RestMethod, a cmdlet capable of sending HTTP and HTTPS requests and is akin to curl on Unix systems. Here, it retrieves the installation script from claude.ai. Once the script is fetched, iex, shorthand for Invoke-Expression, executes the fetched script directly. This method simplifies the deployment process by automating the download and setup procedure, crucial for seamless integration into Windows environments.
Alternative Installation via Homebrew
brew install --cask claude-codeFor macOS users, Homebrew presents another option to install Claude Code. By using the brew install --cask command, you can easily manage and incorporate it into existing toolchains managed by Homebrew. This method is particularly advantageous for users who prefer managing their applications and dependencies through Homebrew for its simplicity, version control, and uninstall capabilities.
In both types of installations, ensure that your system meets the required system specifications and has an active internet connection to fetch the necessary files. The official Claude Code documentation provides further information on system compatibility and any additional requirements.
